Roger R Martella Jr

Lawyer biography

Roger Martella is a partner in the Environmental Practice Group at Sidley Austin LLP. He recently rejoined Sidley Austin LLP after serving as the General Counsel of the United States Environmental Protection Agency, concluding 10 years of litigating and handling complex environmental and natural resource matters at the Department of Justice and EPA.

Mr. Martella’s practice focuses on three primary areas. First, Mr. Martella advises companies on developing strategic approaches to achieve their goals in light of rapidly developing demands to address climate change, promote sustainability, and utilize clean energy. Second, Mr. Martella handles a broad range of environmental and natural resource litigation and mediation. Third, Mr. Martella advises multinational companies on compliance with environmental laws in the United States, China, the European Union, and other nations.

Mr. Martella was unanimously confirmed by the United States Senate as EPA General Counsel. In that role, Mr. Martella served as EPA’s chief legal advisor supervising an office of 350 attorneys and staff in Washington and 10 regional offices. At EPA, Mr. Martella served as Agency counsel on six Supreme Court decisions, including Massachusetts v. EPA (climate change); Defenders of Wildlife v. EPA (finding no Endangered Species Act duty to consult when approving state water program); EPA v. Rapanos and Maine v. S.D. Warren (landmark decisions addressing federal jurisdiction over waters of the United States); Environmental Defense v. Duke Energy (addressing Clean Air Act enforcement against powerplants); and U.S. v. Atlantic Research Corp. (the Court’s most recent decision regarding CERCLA).

In particular, Mr. Martella led the team responsible for developing for the first time under the Clean Air Act the federal government’s climate change legal framework and options in response to the landmark Supreme Court decision Massachusetts v. EPA, which held greenhouse gases to be air pollutants under the Clean Air Act. His efforts included developing a full range of legal options for decision makers related to greenhouse gas regulation, alternative and renewable fuels, the development of regulatory carbon sequestration controls, and the intersection of climate change and natural resource issues including the National Environmental Policy Act and the Endangered Species Act. Recognized for his knowledge on legal approaches to addressing climate change, Mr. Martella focuses specifically on dissecting the extraordinarily complex and interrelated ramifications of climate change on numerous provisions of the Clean Air Act relating to mobile and stationary sources, as well as other laws, such as the ESA and NEPA. Mr. Martella’s experience in this area enables him to work to forecast for clients the likelihood of upcoming regulations and controls in the area of climate change, clean energy, and sustainability, and to develop strategic approaches to be best prepared for such controls. Mr. Martella also focuses on international climate issues, working with Chinese institutes on climate and clean energy issues and advocating for conformity between United States climate rules with the European Union. Since the April 2007 Massachusetts decision, Mr. Martella has been invited to address climate change regulation more than twenty-five times in the United States and abroad.

In addition to climate change responsibilities, Mr. Martella focuses on the challenges in adapting existing and frequently outdated environmental law tools toward new and complex environmental challenges of national and international sustainability, including the increasing demands on industry to promote environmentally sustainable development protecting air, water, land, and human health.

Recognizing deficiencies in the China environmental law framework and the challenges for multinational organizations in understanding the laws on the books, Mr. Martella created the China Environmental Law Initiative in 2007. As part of the initiative, Mr. Martella created the only known website devoted to China environmental laws and organized with the State Environmental Protection Agency (now the Ministry of Environmental Protection) two separate symposia in China. Mr. Martella has served as a visiting professor at the Environmental Law Institute of Wuhan University and the State Environmental Protection Agency, and at Tsinghua University, working with academics, officials and students on developing environmental law frameworks for China. Mr. Martella has testified as an expert on this issue before the United States Congress, worked with numerous government officials at the national and provincial level in China, and has lectured with academics and students at leading universities and think tanks in both nations.

Prior to joining EPA, Mr. Martella most recently served as the Principal Counsel for Complex Litigation at the Justice Department’s Natural Resources Section, where he focused on defending federal decisions relating to public lands, national forests, minerals, federal and tribal water rights and allocations, endangered species, NEPA, and Native American property and reservations. During nearly eight years at the Department of Justice, Mr. Martella maintained an unbroken record of successfully litigating every case he brought to court. His first chair trial responsibility included a 12 week jury trial that returned a $36.9 million verdict, a seven week bench trial that resulted in a $247.9 million judgment, an unbroken record of successfully defending against numerous emergency injunctions brought against timber and mining projects, and successfully defending the Secretary of Interior from a contempt motion at trial. Mr. Martella’s responsibilities in the Natural Resources and the Indian Resources Sections related to federal land use decisions and policy; defense of federal statutes, regulations, and agency action under the APA, ESA, NEPA, and other statutes; competing assertions of jurisdiction and land use control among various government entities; federal programs relating to natural, cultural, wildlife, and marine resources; pollution control issues under Clean Air Act, Clean Water Act, CERCLA, RCRA, TSCA, FIFRA, and EPCRA; and issues related to water, hunting, fishing, and treaty rights. Mr. Martella received among the highest honors at the Department of Justice including the John Marshall Award and the Assistant Attorney General’s Excellence Award.

Mr. Martella graduated from Vanderbilt Law School, where he was Editor in Chief of the Vanderbilt Law Review, and Cornell University, where he studied environmental science. Following law school, he clerked for the Hon. David M. Ebel of the Tenth Circuit Court of Appeals.

Mr. Martella, elected at large to the Warrenton, VA, Town Council, devotes significant effort to public service in his community and was recognized in 2006 as Citizen of the Year by the Fauquier County Board of Supervisors for his public service and volunteerism efforts.

Council on Environmental Quality finalises guidance for assessing climate impact
USA | 22 August 2016

The White House Council on Environmental Quality has issued guidance to provide direction for federal agencies in addressing the effects of greenhouse gas emissions and climate change as they satisfy their duties. Many projects may now require federal permits, approvals or funding from federal agencies and thereby require the preparation of an environmental impact statement or environmental assessment.

Legislative changes will affect companies that manufacture and use chemicals
USA | 04 July 2016

Congress recently passed the landmark Frank R Lautenberg Chemical Safety for the 21st Century Act, the first time the Toxic Substances Control Act has been substantively amended since its enactment in 1976. It is important that all companies that manufacture, use, process, import, export or sell products containing chemicals become familiar with the new regulatory regime.

Federal rule would require indication of whether contractors publicly disclose GHG emissions data
USA | 20 June 2016

The Federal Acquisition Regulatory Council recently published a proposed rule in the Federal Register that would require federal contractors with awards cumulatively exceeding a given threshold to indicate whether they publicly disclose information on their greenhouse gas emissions. The rule would enable the federal government to consider greenhouse gas emissions when deciding what items to procure and which contractors to use.

Fracking: latest environmental regulation developments
USA | 23 May 2016

EPA proposes to expand regulation of oil and gas industry
USA | 21 September 2015

The Environmental Protection Agency recently proposed three significant regulatory actions extending its controls over the energy sector by expanding regulations over the oil and gas industry. This is key to achieving the Obama administration's goal of reducing methane emissions from the oil and gas sector and its overall efforts to reduce greenhouse gas emissions by regulating the development and use of fossil fuels.

DC Circuit curbs EPA Cross-State Air Pollution Rule
USA | 31 August 2015

The DC Circuit has held that emissions limits imposed by the Environmental Protection Agency (EPA) on 13 states under its Cross-State Air Pollution Rule were unlawful. The EPA "overstepped its authority", the three-judge panel unanimously held, by requiring states to cut emissions more than necessary to ensure that other states meet air-quality standards.

Activists petition for federal takeover of Oklahoma disposal programme
USA | 03 August 2015

Several activists have petitioned the Environmental Protection Agency (EPA) Administrator to rescind its delegation of authority to Oklahoma to manage its wastewater disposal programme. According to the petition, the Oklahoma Corporation Commission is failing adequately to restrict the underground injection of oil and gas wastewater and to fine companies that inject wastewater, leading to continued low-level seismic activity.

New York officially bans hydraulic fracturing
USA | 27 July 2015

New York's Department of Environmental Conservation has officially banned high-volume hydraulic fracturing after concluding that it poses risks to public health and the environment. The ban came after a more than six-year evaluation process during which time high-volume hydraulic fracturing was subject to a temporary moratorium.

Key takeaways of Supreme Court decision in Michigan v EPA
USA | 13 July 2015

The Supreme Court recently reversed a decision upholding the Environmental Protection Agency (EPA) Mercury and Air Toxics Standards Rule, which set emission standards for hazardous air pollutants from power plants. The court held that the EPA had excluded the consideration of costs when evaluating whether the regulation of hazardous air pollutants from power plants is appropriate and necessary.

Environmental group challenges federal wastewater permits
USA | 08 June 2015

Environmental group Public Employees for Environmental Responsibility has filed a petition with the Environmental Protection Agency (EPA) Environmental Appeals Board, challenging five federal national pollutant discharge elimination system permits allowing three oil and gas companies to dispose of wastewater in surface streams.
